Subjects have their own language or ‘jargon’ where a few words indicate a whole area of study.
Many ‘topics’ with short identifications or key terms, identifiers, classifications can represent Lifetimes of Study over generations.
We start to learn at a simple level and progress to more complicated levels with increasingly more and more key terms.
The ‘Ice Age’ for example can be a simple explanation or contain hugely complex Scientific and Geographic, Hisorical and Geological information gained by experts over more than a single person or organisations life or timespan!
It can also be across subject boundaries and become for example a media focus (maybe with research) for different age groups!
In English however we look for a different kind of language and its the Grammar aspect that usually requires Key Terms or specific vocabulary like explaining what verbs or adjectives or nouns are.
Fact and Fiction use a different focus and smaller students can mix the two quite easily and thats cool. The world around us is full of ways to trip us up – making a television programme is fact, the content is often fiction using actors even on quiz programmes where you are encouraged to believe the contestants are not actors – thats for entertainment and they want us to believe we could be part of their programme. Similarly documentaries where they are ‘economical’ with the ‘truth or facts’ for timings or keeping the audience watching.
Exam Boards require their Specification language.
They also want specific types of answers
